VALVE-GUARD FOR GASSTO\JE$= Specification of Letters Patent.

Patented June 4, 1907.

Application filed March 26, 1907. Serial No. 364,7e2.

To a, whom. it may concern.-

Be it known that I, THOMAS HALEY, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Valve-Guard for Gas-Stoves, of which the following is a specification.

In gas stoves constructed under present methods, there is always a liability of the valve being opened or left open by mistake, and especially where there are; small children around, it has been found that the valves are often partially opened by. them, thus permitting the gas to escape and rendering possible an explosion with-consequent loss, and damage. i

The object of my present invention is to devise a novel construction of a valve protecting member which is adapted to be readily placed in position on any desired type of gas stove, heater or the like having gas pipes leading thereto, and by the employment of which any inadvertant or careless opening of any-of the valves is positively prevented.

To the above ends my invention broadly consists in a novel construction of a plate which is automatically locked in position when the same is placed on the gas stove.

It further consists of a novel construction of plate, the upper surface of which is deflected so as to form a flush surface with the top of thegas stove and the lower portion of which is provided with angular slots' adaptguard will not be tampered with or improp ed to co-act with the branches leading from the main feed pipe,

It further consists of a novel construction and correlation with'the above mentioned plate, of a locking pawl which is carried by the valve guard and prevents any improper movement of the same when placed in position.

It further consists of a novel construction ofa valve guard having angular shaped slots therein, provision being madewhereby'the valve guard must be moved-in a pluralityof directions before the same'is disengagedfrorn the branch feed pipes in order thatthe' valve erly removed by children or others.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention I have shown in the accompanying drawings one form of a device, since this embodiment has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists may be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentali-ties as herein shown.

Figure 1 represents a perspective view of a valve guard embodying my invention. Fig. 2 represents a side elevation of a portion of a gas stove having a valve guard embodying my invention in operative relation therewith. Fig. 3 represents an end elevation of a portion of a gas stove, the valve guard, main feed pipe and valve lever being shown in section. Fig. 4 represents a side elevation of a valve guard showing a modified form of a locking recess. l

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings :1 designates a gas stove of any usual or conventional type and having preferably an off-set 2 at the front end thereof.

3 designates the main feed pipe which is supported, in the present instance by the hangers 4 carried by the gas stove 1.

5 designates branch pipes leading from the main feed pipe 3 to the burners (not shown).

6 designates my novel construction of valve. guard which, in the present instance comprises a plate 7, the upper end of which is deflected as seen at S in a substantially horizontal plane so that it forms a flush surface with the top of the-stoveas is clearly indicated in Fig-3.

9 designates a series of slots angularly in-- clined to the bottom of the plate, from which extendangular slots 10, it being noted that the number of these communicating slots 9 and 10 depends upon the number of branch feed pipes 5 which are employed. The ex tensions 11 formed by the slots 9 are rounded on their under side, as is clearly indicated at 12', in Figs. 1 and 2. The vertically extending portion of the plate 7 has its end cut away as indicated at Band 14 in order that the late may pass between the hangers 4 and ave longitudinal movement therebetween,

i of which is pivoted at 18 to the plate 7, said pawl having fixed thereto a suitable handle 19, the pin of which co-aets with the cam slot j 20 in the plate 7', asis clearly apparent fron1 Figs. 1 and 2. The pawl 17 is provided on its under side with a face 21 from which extends angularly a face 22 so that when the pawl/17 is permitted to assume its lowermost position said face 22 will engage one of the hangers 4.

In order to prevent, in a more positive manner, any improper removal of the valve guard 6, it is advantageous under some conditions to employ a slot such as is shown in the embodiment seenin Fig. 4, in which the slot 10 has communicating therewith on its upper side, a recess 23 preferably having a semi-cylindrical contour in order that the wall of the recess 23 will closely engage the branch feed pipe 5. The branch feed pipes 5 have located therein a valve 241 of any desired type.

The operation of my device will now be readily apparent: When it is desired to place the valve guard in position the operator lifts the same by means of the handles 16 and 19 and brings it into such a position that the slots 9 register with the branch feed pipes 5. The valve guard is permitted to descend until the branch feed pipes engage the slot 10, whereupon the valve guard is moved to the right The operator now releases the handles 16 and 19 and when the handle 19 is released it will fall of its own weight so that the face'22 will said hanger.

closely engage one side of the hanger 4, it be ing a parent that thewall 15 of the valve guart will closely engage 'the opposite side of It will be apparent thatwhen a valve guard embodying my invention is in position that all of the valves 24 will be concealed and that it will be impossible to open thesevalves until the valve guard is removed, which is done by gras ing the handles 16 and 19 and moving the va ve guard to the left until the slots 9 register with the branch feed pipes 55, whereupon the valve guard may be readily removed, as will be apparent to those skilled in the art. In order that the valve guard may be more easily placed in position the'under side of the same contiguous the slots 9 is preferably rounded.

It will now be apparent from the foregoing that I have devised a novel and useful con- .sai

embodies the features of "advantage enumerated as desirable in the statenient of invention and the above-description and while I have in the present instance shown and de.'

scribed the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be un derstood that the sameis susceptible of modification in various particulars without departing from the sp1rit and scope of the in vention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Let.
